Smith Study on blood pulse photoplethysmography signal on toe under different body posture and lower limb height Loughborough University 2016 Photoplethysmography Non-invasive Body posture Lower limb Blood pulse signal Mechanical Engineering not elsewhere classified 2016-08-05 08:55:12 Journal contribution https://repository.lboro.ac.uk/articles/journal_contribution/Study_on_blood_pulse_photoplethysmography_signal_on_toe_under_different_body_posture_and_lower_limb_height/9547538 Under two body-postures (supine and 45° reclining) the blood pulse signal on toe was detected via non-invasive photoplethysmography technique while the lower limb was passively raised in different height. The regulations of blood pulse volume and lower limb height were found and their relation was described through curves in figures.
